WALTERJ. TIDD, OF SPRINGFIELD, MASSACHUSETTS, ASSIGNOR. TO TIDD RECORDING CLOCK COMPANY, OF SPRINGFIELD, MASSACHUSETTS, A CORPORATION OF MASSA- CHUSTETTS.

WATCHMANS TIME-RECORDER.

Application filed March 21, 1917, Serial No. 156,417.

To all whom it may concern Be it known that I, lVALTEI: J. TIDD, a citizen of the United States of America, residing in the cit of Springfield, county of Hampden, and tate of Massachusetts, have invented certain new and useful Improvements in Watchmens Time-Recorders, of which the following is a specification.

This invention relates to improvements in watchmens time recorders or clocks, andis particularly designed for use by policemen or other watchmen during their regular trips of inspection to record the time he makes his regular trips or beats. The invenvention, broadly, comprises a clock mechanism which is mountedin a suitable inclosing casing with means for detachably connecting the inclosing case to the inside of a door or other part of the building, preferably, to the inside of the outside door of a store or other place of business. The clock mechanism is provided with means for supporting a dial, which shows numerals and spaces indicating either twelve or twentyfour hours, is carried by the hour post of a clock; Suitable means are provir ed for perforating this dial by the'operator from the outsideof the door. A suitable device is also provided for positioning this dial.

The invention further comprises means for securing, the dial to the hour post, whereby a new dial may be readily applied and the old one removed. A further object of the invention is to: provide a plate device for readily attaching the clock case to the door, and means for attaching the clock case to the plate. These and other objects will ap-- pear in the body of the specification and will be particularly pointed out in the claims.

Referring. to the drawings:

Figure 1 is a vertical sectional view throu' the axis of the clock inclosing casing, il ustrating the perforating rod which extends through the door, and the dial which is engaged by the perforating point;

Fig. 2 is a view similar to Fig. 1 but illustrating on an enlarged scale the dial perforating mechanism, also illustrating the clip device for securing the paper dial to the hour post and the plate carried thereby;

Fig. 3 is a front elevational view of the dial showing the flat spring clip which se v Specification of Letters Patent.

cures the dial to the hour post, the clip being formed with a slot to receive a pin on the hour post, and a cut-out portion at the end thereof for receiving a pin for adjusting the clip on the hour post;

Fig. 1 is a modification of the perforating mechanism in which the perforating pin is operated by a spring on the clock movement instead of on the attaching plate;

Fig. 5 is a view showing the plate that is detachably secured to the inside 01' a door and to which the clock casing is hinged. This view shows the clock casing in a lowered or open position, and the pin operating spring secured to the plate;

Fig. 6 is a detail view of the detachable hinge connection between the clock casing and its attaching plate.

Referring to the drawings in detail: 1 indicates the door or other part of the building, 2 is an attaching plate that is secured to the inside of the door and to which the clock casing 3 is pivotally attached by means of a hinge which is indicated as a whole at 4C. The clock movement, as a whole, is indicated by the numeral 5 and the usual wind ing key at 6 and hand setting button at 7, which operates the hour post 7' in the usual way. 8 is a metal plate on which the paper disk 9 is placed. This plate is operated by the hour post 7 and, therefore, rotates therewith. This dish is secured in place by means of the spring clip 10, shown in front elevation in Fig. 3 and comprises a strip of spring metal having the slotted portion 11 to receive the pin 12 on the hour post 13. The end of the clip is cut out, as indicated at 14; to re ceive the pin 15. It will be seen that the graduated paper disk 9 may be removed by simply lifting the cut out end portion of the strip 1080 as to disengage the same from the pin 15 then slightly turning the spring clip 10 so that the pin 12 registers with the slot 11, whereby the clip as a whole can be removed. The pin 15 serves the further purpose of correctly positioning disk 9 so that when the same is placed on the plate 8 the hour divisions will correspond with the correct time. Extending through the door 1 is the slidable rod 16 having an operating head 17. The end of this rod is formed with an enlarged head 18 which engages a spring 19 that is attached to the inside of the plate 2,

as clearly shown in Figs. 5 and 6. This spring serves the purpose of holding the rod 16 in a normally extending position. WVhen the operator pushes the rod 16 inward the spring 19 is bent or flexed so as to cause the sharpened point 20 that is carried by the spring 19 to perforate the paper disk 9. The point 20 passes through the retaining clip 21 which clip is for the purpose of preventing the paper from sticking to the sharpened point when the spring 19 and the pin 20 is retracted, two of the perforations being in dicated in Fig. 3 at 22. The plate 2 is secured to the door 1 by means of the bayonet connection which comprises enlarged openings 23 and the screw head 24 which passes through this opening and then the shank of the screw enters a smaller portion of the slot 23. The casing 3 is locked to the plate 2 by means of the spring clip 25.

Referring to the modification shown in Fig. 1: Instead of having the spring 19, shown in Fig. 5, a compression spring 26 is located on the rod 27 of the clock movement. Also mounted on this rod is an angular shaped plate 28 engaging the head 18 of the pin 16. The sharpened point 20 is carried by the plate 28. It will be seen that when the rod 16 is operated this plate will be moved on the rod 27 against the compression spring 26 and the perforation of the paper disk is effected in the same manner as be fore described. One of the important features of the present invention is that the operating pin 16 is entirely disconnected from the clock case or clock movement, thus making the recording device very easy to install. Another advantage is that the changing of the disk or dial 9 can be readily accomplished by simply lowering the casing 3, removing the clip 10 and substituting a new paper disk in its place. Fig. 6 illustrates in detail the construction of the hinge connection 4 between the plate 2 and the clock casing Attached to the casing 3 is a pin 26 by means of the clip or bracket 27, the outer end of which is formed with a projection 28', which enters the slot 29 of the complemental hinge part 30. The projection 28' can only enter the slot 29 as the casing 3 and plate 2 are in the same plane. The projection 28' prevents the casing 3 from be coming detached from the plate 2 when the same is opened to the position shown in Fi 5. It is understood that various modifications embodying the above principles may bemade without departing from the spirit and scope of the invention. Another important feature of the present invention is that it does not require any change in construction of the clock mechanism since the paper dial is readily detached to the hour post of the clock.

What I claim is:
